Spray Foam Insulation Before & After Photos

this homeowner first reached out because his radon levels were still dangerously high, even after installing two mitigation systems from another contractor. Something wasn’t adding up. When our team inspected the space, we uncovered the full picture: Not only was radon still entering the home, but water was also seeping up through the floor, especially in the corners where the wall and floor meet. Two problems. One vulnerable foundation. And a family counting on us to get it right.

The Challenge: A Monolithic Foundation

Because the home was built on a monolithic foundation, we couldn’t use a standard waterproofing approach. Cutting into the wall‑floor joint would risk the structural integrity of the entire slab. So we turned to our dual‑stage waterproofing system engineered specifically for situations where precision matters more than brute force.

The Fix: Protecting the Structure While Solving the Problem

1. Waterproofing Without Compromise

• We jackhammered a trench several inches off the wall‑floor joint to avoid weakening the monolithic slab.
• We installed our perforated drainage pipe and gravel, tying it directly into the sump pump to carry water safely out to daylight.
• Then we applied DryTrak along the wall‑floor joint, positioned in front of our weep holes so every drop of water is captured and expelled.

This system keeps the foundation strong while keeping the basement dry.

2. Radon Sealed Out for Good

With the water issue under control, we addressed the radon problem at its source. We applied three inches of closed‑cell spray foam across the crawl space floor and sealed the rim joist—creating a continuous, airtight barrier that prevents radon from entering the home.

The Result: Safety, Comfort, and Peace of Mind

Today, this homeowner can finally rest easy. No more water intrusion. No more radon infiltration. Just a safe, protected home where his familyand especially his grandkids can breathe easy and enjoy the space without worry. They couldn’t be happier with how the project turned out, and the peace of mind that came with it is priceless.

A builder contacted us to insulate their newly constructed home. We sealed the thermal envelope from top to bottom using closed-cell spray foam, ensuring year-round energy efficiency.

We applied 5.25 inches of spray foam to the exposed roof slopes, 3 inches to the gable ends, and 3 inches to the first floor. We also applied 3 inches of spray foam to the rim joist. Most areas reached an impressive R-value of 21, except for the roof slopes, where we achieved an R-value of 38.

The builder was thrilled with the results and looks forward to more projects with us, including insulating their own home in the near future.
